Researchers have shown how auditory working memory and musical aptitude are intrinsically related to reading ability, and have provided a biological basis for this link. 

Researchers from the Auditory Neuroscience Laboratory at Northwestern University tested children on their ability to read and to recognize words. 

This was compared to the extent of their auditory working memory (remembering a sequence of numbers and then being able to quote them in reverse), and musical aptitude (both melody and rhythm). 

The electrical activity within the children's brains was also measured as auditory brainstem responses to rhythmic, or random, sounds based on speech. 

The team lead by Dr Nina Kraus found that poor readers had reduced neural response (auditory brainstem activity) to rhythmic rather than random sounds compared to good readers.
